[Bug 1886279] Re: simple-scan pdf compression
As a user I like to know what happens inside things. I would like a combo-box in "preferences" giving the following choices for saving to pdf: 1) Jpeg or zlib (smallest one chosen for each image) -> default 2) Jpeg only (lossy) 3) Zlib only (lossless) Your proposition is much simpler, however it remains opaque to users. It depends on the audience you target. Note: I just installed everything to disable jpeg compression in a local build (quick hack) and debug the program. It is my first time with Vala + Gtk. So we may have more technical discussion now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886279 Title: simple-scan pdf compression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1886279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1886279] Re: simple-scan pdf compression
The code responsible for encoding pdf is available here: https://gitlab.gnome.org/GNOME/simple-scan/-/blob/master/src/book.vala#L348 It is comparing jpeg with zlib: https://gitlab.gnome.org/GNOME/simple-scan/-/blob/master/src/book.vala#L479 How would you like to change it? What do you think about setting quality to maximum, force zlib compression? ** Changed in: simple-scan (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886279 Title: simple-scan pdf compression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1886279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1886279] Re: simple-scan pdf compression
** Description changed: Hello, PDF compression cannot appropriately be configured. Having taken a look at the latest source code of simple-scan: - 1) simple-scan compresses each image in GIF or JPG depending on the compressed size (it keeps the GIF version if it is smaller than the JPG) - 2) the "quality" setting only applies to JPG + 1) simple-scan compresses each image in ZLIB or JPEG depending on the compressed size (it keeps the ZLIB version if it is smaller than the JPEG) + 2) the "quality" setting only applies to JPEG - With this in mind, it is impossible to use simple-scan to create a PDF - full of lossless GIFs for archiving documents where we want to keep - quality at the expense of the size. + With this in mind, I think it is impossible to use simple-scan to create + a PDF full of lossless ZLIB images for archiving documents where we want + to keep quality at the expense of the size.
